E4od codes

[Zbmonster]

I was driving my truck and out of nowhere my od light started flashing so I used my scanner and got the codes 74 and 65 so I put a new boo switch in and unplugged the batteries drove it for about 30 min and did it again when it starts flashing it doesn't shift hard or anything so what do you guys think it is

I have the following:

65: TCS not changing state.

74: brake not actuated during on-board diagnosis.

When you pull the codes, either by the CEL light or a scanner, the brake peddle has to be actuated all the time during the code pull, That's why your getting the 74 code, you should have gotten a 23 code also.
